This device has been designed for machining stationary workpieces with rotating tools. It consists of a revolving head with an inserted tool slide having a radial stroke U axis. The slide movement is controlled by a CNC operated bruschless motor. in operation, for example, when boring, turning, threading, etc, the tool slide moves in its guideways. The fast-acting clamping mechanism of the tool
holder is located in the radial slide. This is dimensioned so that tool location and clamping are kept within the head diameter. In this way avoiding excessive tool over-hang such as maybe found in other facing heads. This tool clamping system guarantees maximum rigidity bacause the tool has a wide supporting plate so that it operates effectively even with high metal removal. 

MACHINING CENTRE
Machining centre DS 450/130C is equipped with two working systems: facing and turning head with two tool locations on a slide moving radially DJ with the capability of turning from small up to big diameters with the same tool;
high speed spindle equipped with a quill placed under the facing and turning head to carry out drilling, tapping and other operations at high speeds. This robustly built machine has been designed so as to achieve excellent chip forming and is equipped with sealed guards round the machíne which prevent any escape of chíps and coolant. All mechanical parts moving in the head are made of heat
treated steel and lubricated by means of an oil circuit specially designed for this purpose. The machine bed is made of welded and stabilized steel. The head is made of Meehanite cast iron. All slides of the axes are fitted with linear rollerways and the kinematic mechanisms are constructed wíth preloaded, double lead, recirculating ball screws and Bruschless type motor. All mechanical parts of the facing and turning head are dimensioned so as to quarantee high chip removal. All movements are controlled by CNC. When facing, the tool works most efficiently
wíth the continuous cutting program. The quill retracts within the spindle only when the latter is stopped. The rotating
table with continuous movement 360.000 divisions is provided with slideways and locations for the pallet.
